Structure-Medium Interaction and Design Procedures Study. Volume I. Analysis Method, Theory, Verification and Applicability. (2005)

Abstract
The purpose of this study was to develop an analysis method for the computation of loads and motions of buried structures subject to nuclear attack, and to utilize this method for the development of design information for such facilities. The achievement of this objective required the accomplishment of several interrelated tasks. These included the development of the numerical analysis technique, the verification of the analysis technique's capability to perform the required computations, the demonstration of the analysis method for a set of realistic problems, and the development of design information for hardened missile facilities. It is recognized that the problem of structure - medium interaction is truly three-dimensional. The current state of the art, however, does not include adequate techniques or computational facilities for such analyses in three dimensions. Recognition of these facts at the outset of this study led to an approach which uses basic two-dimensional analyses coupled together to represent the most important features of the three-dimensional wave diffraction problem for blast loaded silo structures. The direct stiffness version of the finite element analysis technique (FEAT) is used to construct the analysis models for structure - medium interaction. (Author). See also Volume 2, AD-506 198.
